The invention discloses a flight control system and method for a vertical take-off and landing unmanned aerial vehicle. The flight control system comprises a thrust driving module and an angle sensor. When the vertical take-off and landing unmanned aerial vehicle is in a take-off and landing state, the angle sensor is used for acquiring target angle data and sending the target angle data to a controller; and the controller is used for enabling a thrust motor to drive a thrust propeller to rotate according to the target angle data till that the orientation of the thrust propeller is parallel to a horizontal direction. In the take-off and landing state, the deviation angle of the thrust propeller can be obtained in real time, the thrust motor is controlled in time to drive the thrust propeller to rotate, the orientation of the thrust propeller is made to be parallel to the horizontal direction, and meanwhile the thrust propeller is locked to the position with the largest distance from the ground or a ground obstacle through a motor brake; therefore, collision events of the unmanned aerial vehicle in the take-off and landing process can be reduced to the maximum extent; and in addition, interference to other equipment is also avoided.
本发明公开了一种垂直起降无人机的飞行控制系统及方法,所述飞行控制系统包括推力驱动模块和角度传感器;在垂直起降无人机处于起降状态时,角度传感器用于获取目标角度数据,并发送至控制器;控制器用于根据目标角度数据控制推力电机驱动推力螺旋桨转动,直至使得推力螺旋桨的朝向与水平方向平行。本发明能够实现在起降状态时,实时获取推力螺旋桨偏离的角度,并及时控制推力电机驱动推力螺旋桨转动,使得推力螺旋桨的朝向与水平方向平行,同时将推力螺旋桨通过电机刹车锁定在与地面或地面障碍物距离最大的位置,从而能够最大限度的减小无人机在起降过程中的碰撞事件发生;另外,也避免了对其他设备造成干扰。
